Association between Gustave Roussy Immune Score and delay in discharge among children and adolescents with mycoplasma pneumoniae pneumonia: a retrospective cohort study
Abstract
Background Mycoplasma pneumoniae pneumonia (MPP) is one of the leading causes of hospitalization and death in children. Epidemiological studies have confirmed that single blood indicators such as the neutrophil-to-lymphocyte ratio (NLR), lactic dehydrogenase (LDH), and albumin (Alb) levels are associated with the prognosis and length of stay (LOS) of patients with MPP. In this study, we aim to evaluate the association of the GRIm score with the LOS and compare its strength of association with that of its individual components. Methods We recruited 786 children with MPP who were admitted to the Affiliated Hospital of Shandong University of Traditional Chinese Medicine during the period between 2014 and 2021. The end of follow-up was discharge. Univariate and multivariate logistics regression models were used to explore the association between the NLR, LDH, Alb as well as the GRIm score with the LOS among our cohort, with odd ratios (ORs) and 95% confidence intervals (CIs). The receiver operating characteristic (ROC) curve, the net reclassification improvement (NRI) index, and the integrated discrimination improvement (IDI) index were used to compare the predictive efficacy of the GRIm score with the NLR and LDH and in predicting the LOS among children and adolescents with MPP. Results After the application of the inclusion and exclusion criteria, 389 eligible children and adolescents with MPP were included, with a mean age of 5.21 (±2.59 years). After adjusting for…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 786 participants or records.
